Chemistry Panel (Comprehensive Metabolic Panel)
The Chemistry Panel, also called a Complete Metabolic Panel, is a crucial test done during annual exams. It provides important markers for understanding cardiovascular risk, metabolic function, electrolyte status, liver and kidney function.
Electrolytes, Acid-Base (pH) Balance and Minerals
- Carbon Dioxide

- Alkaline Phosphatase (ALP)
- Alanine Aminotransferase (ALT)
- Aspartate Aminotransferase (AST)
- Bilirubin (total)

Fasting: Yes. Fast for 8-10 hours prior to test.
Water: Drink plenty of water to stay well hydrated.
Medications: Take all medications as prescribed.

Result turnaround times are estimates and not guaranteed. Due to factors outside of our control, such as weather, holidays, confirmation/repeat testing or equipment maintenance, our lab may require additional time to complete tests.
Glucose. The kidneys filter glucose out of the blood. Elevations in glucose can indicate pre-diabetes or diabetes and place a significant strain on the kidneys.
Electrolytes, Acid-Base (pH) Balance and Minerals
Calcium. Low calcium is common in people with kidney failure. Other diseases that have been associated with abnormal blood calcium such as thyroid disease, parathyroid disorder, malabsorption, cancer, or malnutrition.
Carbon dioxide. Carbon Dioxide (CO2) is a waste product eliminated by the body through breathing and by the kidneys. Carbon dioxide is a measure of the amount of carbon dioxide gas in your blood and assists in evaluating how acidic your blood is and your electrolytes. Electrolytes help balance the levels of acids and bases in your body. Most carbon dioxide in your body is in the form of bicarbonate, which is a type of electrolyte. Electrolyte imbalances can occur in kidney diseases, lung diseases, and high blood pressure.
Chloride. Chloride is an electrolyte that can give an indication of acid-base balance and hydration status. It works with other electrolytes such as CO2, potassium and sodium.
Potassium (K+). Potassium (K+) is a major mineral inside cells. Potassium is excreted by the kidneys and its concentrations depend on many factors, including aldosterone, sodium resorption, and acid-base balance.
Sodium (Na+). Sodium (Na+) is the major mineral in the spaces surrounding cells, called the extracellular space. Sodium plays a major role in how much water flows into and out of cells. Serum sodium levels are the result of a balance between the dietary intake of sodium and its elimination by the kidneys.
Blood urea nitrogen (BUN). The BUN test is an indicator of kidney health, is primarily used with creatinine to help diagnose kidney disease, and to monitor people with acute or chronic kidney disease. Urea is a breakdown product of protein, and the BUN level can be an indicator of how well the kidneys are filtering the blood.
BUN/Creatinine Ratio. The BUN/Creatinine Ratio is used to diagnose acute or chronic kidney disease. Since BUN and creatinine are both filtered in the kidneys, the two together provide an overall kidney function.
Creatinine. Creatinine is found in high concentrations in muscle. When muscle breaks down it releases creatinine, which is filtered from the blood by the kidneys. Creatinine is one indicator of kidney health.
Estimated glomerular filtration rate (eGFR). Estimated GFR is a measure of kidney function and is calculated based on the level of creatinine in the blood.
Albumin. Albumin is a protein made by the liver. It keeps fluid from leaking out of blood vessels and transports hormones, nutrients and drugs. Albumin is measured to help diagnose liver or kidney disease and to assess nutritional status.
Globulin (calculated). Globulin is one of the major proteins in the body. It transports proteins, carries minerals and acts as immunoglobulins as part of the immune system.
Albumin/Globulin Ratio (calculated). The albumin globulin ratio (calculated) can be used to gauge the production of immunoglobulins. A low ratio may reflect the overproduction of globulins, whereas a high ratio suggests under production.
Alkaline Phosphatase (ALP). ALP can be found in many tissues, but it is mostly found in the liver, biliary tract, and bone. Measuring this enzyme is important for determining liver and bone disorders.
Alanine Aminotransferase (ALT). ALT is an enzyme found predominantly in the liver. ALT is measured to screen for liver damage and to diagnose liver disease.
Aspartate Aminotransferase (AST). AST is an enzyme that’s found in the liver as well as other organs throughout the body, including the heart, kidneys and muscles. AST is measured to screen for liver damage and to diagnose liver disease.
Bilirubin (total). Bilirubin is the breakdown product of red blood cells in the body. Total bilirubin is measured to screen for or monitor liver disorders or hemolytic anemia.
Protein (total). Albumin and globulin make up most of the protein found in the body and are involved in a variety of biological processes, including the regulation of osmotic pressure, transport of drugs, hormones and enzymes.
